CALIFORNIA ATOMIZER Application filed September 4, 1926.

ing of liquid fuels such as crude oil or other hydrocarbons, and by which a'thorough atomizing of t-he fuel and intimate mixing thereof with air will be eected, and the mixture ejected from the atomizer at a high velo locity, to the end that a highly combustible mixture will be obtained, which when burned will produce a practically complete combustion.

Other objects and advantages will become '15 apparent as the description proceeds.

In the accompanying drawings,

Figure 1 is a vertical longitudinal section through the atomizer;

Figure 2 is a section on line 2 2 of Fig- 2o ure 1.

In order to effect disintegration of the oil through an atomizing process, use is made of an atomizer including a housing 11 closed at one end by a cap 12, and provided at one side preferably adjacent to said cap with an inlet opening 102L in order that air under suitable pressure may be introduced to said housing. Located within the housing is a nozzle 13 comprising a rotary section 14 and a staec tionary section15. The stationary section 15 is formed with a cylindrical enlargement 16 and a reduced branch 17, in which latter is formed a bore 13. The branch 17 is threaded into the head 12 axially thereof, and same finds connection with an cil supply pipe 19.

bers 24-24 are spaced apart by a sleeve 26 and, as illustrated, said members are mounted on the hollow tube 27 of the revolving section of said nozzle 13. The forward end of the tube 27 is shouldered at 28 and the rear end if threaded to receive a clamp nut 29, whereby Serial N0. 133,613.

the members 24-24 are held fast to the tube Screwed or otherwise suitably secured to the revolving sect-ion 14 of the nozzle is an impact member 30 comprising integral, respectively graduated, frusto-conical cones 31 and 32, the largest diameter of the cone 32 being slightly less than the internal diameter of the forward end of the aforementioned housing 11 so that an annular space 33 is formed therebetween.

lVithin the cylinder 16 axially of the tube 27 is a jet pipe 33LL closed at its forward end at 34 and provided liust rearward of said forward end with a radial orifice 35 which opens toward the extreme inner or reduced end of the cone 31. The rear end of the jet pipe opens to the bore 18 which leads to the source of fuel supply.

Extending through the tube 27 in spaced relation to the walls thereof is an air tube 36 whose forward end extends beyond the closed end 34 of the tube 27, and whose rear end extends into the housing 11 where it opens thereto. Mounted on the revolving section 14 of the nozzle 13 is an impeller 37 having radial blades 38.

The forward or enlarged end of the cone 31 is arranged in overlapped relation to the walls of the cone 32 at the small end of the latter.

00M decomposition I have described the characterizing instrumentalities of means or mechanism for effecting decomposition of petroleum with the consequent breaking up of the molecules and the production'of both lighter and heavier hydrocarbons, called cracking7 and the manner of functioning of the partslis set forth as follows: A

' Crude petroleum under pressure is admitted to the nozzle 13. Air under suitable pressure is admitted to the housing 11 by way of the intake opening 10a. The petroleum is fed through the jet tube 27 where it finds escape by way of the orifice 35. From said orifice, the petroleum is forced against the impact surface of the small end of the cone 31. During the operation of continuously feeding the petroleum through the nozzle, the f function of the respective cones 31 and 32 is to set up rotation of the petroleum within said cones or to impart thereto a whirling motion. This causes a bombardment of the petroleum against the entire inner wall1 sur.- faces of said conesto the end that the molecules are thoroughly broken up. The overlapped relationof the respective cones serves toY further augment. the decomposing action. as the fluid leaves the small' cone and enters the large one. As the parts function in the manner aforementioned, air under press-urefrom the tube 36 and the opening l0a is drawn into the small end of'th'e cone 3l; whene it emerges axially thereof from in front of the closed end: 342 of thejet'pipe; Il find'th'at the air mixing with the elements wit-hin the" conesll and)J additionally lendsto'the'effect of t'hecon'es toward rapidi decomposition of.Y the elements.

Incident to'the'fact'thatfair. under pressureV is constantly entering the housing 1L itt manifestly followsfth'at' this airactsto' drive the impeller 37 to effect rotation.e of he nozzle portion 14 anditscones 3l and 32. Blast iniduced at the space between'the lange end of the cone 32.- and the forward endaof the housing. l'l assists the decomposing-action;-v

Due'to the fact'that the'initiahdischarge.of the petroleum isin af radial directioni at* the innerendofY the coneY 3L, thev impact action; herein referred to is-progressively augmented sothat when the elementsreach'the'large dis charge end of the cone 32 a completecrack V ing` of. theI oilz' hasrbeeneffected and.y by the action of; the air from` openingsV 10a-supplementediby thefprevailingfgeffect of air issuing from -the pipe/36., the 'decomposedpetroleum is expelled spray-like from.l saidf cone."

Although I: have herein shown and' dejscribed4 only on e'f'orm of: atomilZen-embodying my invention, it is to be understoodthatvarouschanges and:modii'ca-tionsmayl be -made thereinxfwithout departing from ther spirit' of the `vinvent-ion andA the spirit and! scope of the appended claim.
